Product Specifications

Technical details and manufacturing context for Control Solenoid

Definition
A control solenoid is an electromagnetic component within the Color Change Module that precisely regulates the flow of colored fluids or dyes by converting electrical signals into mechanical valve movement, enabling rapid and accurate color switching in manufacturing processes.
Working Principle
When electrical current flows through the solenoid coil, it generates a magnetic field that moves a ferromagnetic plunger, which opens or closes a valve port to control fluid flow. De-energizing the coil allows a spring to return the plunger to its default position.
Common Materials
Copper wire, Ferromagnetic core, Stainless steel housing, Elastomer seals
Technical Parameters
  • Valve port diameter determining flow capacity (mm) Customizable
Components / BOM
  • Solenoid Coil
    Generates electromagnetic field when energized
    Material: Copper wire with insulation
  • Plunger Part
    Moves to open/close valve ports under magnetic force
    Material: Ferromagnetic steel
  • Valve Body
    Houses fluid passages and provides mounting interface
    Material: Stainless steel
  • Return Spring Part
    Returns plunger to default position when coil is de-energized
    Material: Stainless steel spring wire

Frequently Asked Questions

What materials are used in this control solenoid for durability?

This control solenoid features copper wire for efficient conductivity, a ferromagnetic core for strong magnetic response, stainless steel housing for corrosion resistance, and elastomer seals for reliable fluid containment in industrial environments.

How does this solenoid control fluid flow in color change systems?

As an electromechanical actuator, the solenoid uses electromagnetic force to move its plunger, which opens or closes fluid pathways in the valve body. This precise control enables accurate color switching in manufacturing systems.

What are the main components in the solenoid's bill of materials (BOM)?

The key BOM components include the solenoid coil (generates magnetic field), plunger (movable core), valve body (fluid pathway structure), and return spring (ensures proper reset position).
